Setting SMA ShadeFix

You can set the time interval in which the inverter has to determine the optimum operating point and to optimize the MPP of the PV system. In battery-backup operation mode, SMA ShadeFix is automatically deactivated.

Procedure:

  1. Follow the procedure for changing the parameters Changing parameters.
  2. In the parameter group DC-side > DC settings > SMA ShadeFix, set the parameter Time interval of SMA ShadeFix and set the required time interval.
  3. Set the desired time interval. The ideal time interval is usually six minutes. This value should only be increased if the shading situation changes extremely slowly.
